Local Medical Issues

Heartworm disease is transmitted through the bite of a mosquito carrying the microscopic heartworm larvae. Mosquitoes become carriers by biting an already infected animal and then subsequently biting other healthy ones. As a result, heartworm disease is a problem virtually everywhere there are mosquitoes.

One Bite Can Infect Your Pet

In dogs, the worms live in the heart and large blood vessels around the heart and lungs, where they can damage tissues and lead to heart failure and pulmonary disease. In some cases, the worms can obstruct other large blood vessels, leading to liver failure and kidney disease. Severe cases can be fatal.
In cats, the worms are found in the heart, lungs or a pulmonary artery. While cats are less susceptible to heartworm infection than dogs, their body's reaction to the worms can be more intense. Feline patients can become severely ill or even die suddenly from just one or two worms.

The Good New Is that It's Easily Preventable

Step #1: Get your dog and cat tested

A simple blood test can detect whether or not your pet has been exposed to heartworm infection. Additional diagnostic tests that may be used to determine the extent of heartworm infection include radiography and ultrasound.

Step 2: Start them on preventive medicine

Depending on your individual pet and personal preferences, your veterinarian will recommend either monthly oral or topical heartworm preventive medication.

Many of these medications also control other internal parasites, such as roundworms, hookworms, and whipworms.
